During the normal operation of the Warping plant, the warp'yarns 34 travel from the bobbins 36 mminted the creel through the space between a-stationary gripping means 38 and a may; able gripping means 40 of the storage device 22 and thence through a, reed 42 tc a beam" 441m serted into the warper 20 and driven by an electromotor 46: v v

The storage device 22 serves teunwind a per-'- tion of the warp 3 lfroni the beam 44 in ase of breakage of yarnby displacing'tlie movable grip ping means 40' from its inactive position shown in full lines into its active position 40" shown in dash and dot lines. Reference isha'd to myPatent #2',302,7-00 relating to a Storage'devicefora temporary unwinding of a portionof the warp from the beam on a warping or beaiiiin'g' machine,issu'e'd on November 24,1942, for a 'm'ore detailed description of' the construction and opertion oft-he storage deVic'eZZ.

Although Fig. 1 illustrates al referredarr'angement of a warping plant whereinthe'" warper is used in combination with a storage device of a certain construction, the" warper according. to

the present invention may beiused' Witliout'a storage device, if desired. Furthermore; if the warper is used in combinationwith} a storage device; thelat'ter may-be of any suitable type;

As best snows inr'ig'sj zanm; thedrivingelectromotor 40 is mounted on theme-1e 48 6f the warper 20, Theelec'tro'motor is directly coupled with a driving means or driving head 50 keyed to the shaft '52 of the electromotor and held in its position by a nut 54, so that the driving head rotates at the same speed as the shaft of the electromotor. The electromotor may be started by means of the start switch 382 and may be arrested by means of the stop switch 4I4, both switches being arranged in a box mounted on the frame of the warper as shown in Figs. 1 and 2. A bracket 55 (see Figs. 1, 2, 4, and 5) is swingably mounted on a stationary rod 58 carried by supporting elements 60 and held in its position by set screws 62. The supporting elements 60 are slidably arranged on rods 84 carried by stationary parts of the frame of the warper. The supporting elements 60 may be held in any adjusted position by means of set screws 86 (see Fig. 4). For the purpose of balancing the weight of the bracket 56 and the parts connected therewith in the intermediate positions of the bracket between its operative upright position shown in Fig. 4 and its inoperative horizontal position shown in Fig. 5, two torsion springs 68 are wound around the rod 58, one end of each torsion spring being secured to the rod, the other end of each torsion spring being secured to the bracket, The bracket may be held in its upright position by means of a. locking screw I0 swingably mounted on a stationary extension I2, which may be engaged with a complementary locking member I4 on the bracket.

A hearing I6 arranged on the bracket 58 carries the shaft I8 of'an idling head .80. The rotatable shaft I8 rests on rollers 82 of the bearing and is arranged withjplay in the bearing, i. e. the shaft may also be shifted in the direction of its longitudinal axis. One side of a thrust ball bearing 84 'mounted on a shiftable rod 86 extending through a hole in a cover plate 88 of the bearing I8, is in contact with the end of the shaft I8 of the idling head. A spring 90 arranged between theplate 88 and the other side of the ball bearing 84 tends to urge the latter against the end of the shaft I8. The idling head 80 and its shaft 18 may be shifted to a certain extent in the direction of the arrow A against the action of the spring 80. The movement of the rod 86, ball bearing-84, shaft 18 and idling head 80 in the opposite direction under the action of the spring 80 is limited by a set collar 92 secured to the projectingend of the rod 86.

A gear 94 keyed to the shaft I8 of the idlin head meshes with a. pinion 86 keyed to the shaft of a shut off counter 98 mounted on top of the bearing I6. The shut off counter 88, which may be of any well known type, serves to cause an autom'aticstoppage of the warper as soon as the beam 44 has performed a predetermined number of revolutions for which the shut off counter has been set.

As best shown in Figs, 3 and 4, a pair of' adjustable rest bars I00 is arranged in the space below the space occupied by a beam 44, Each rest bar comprises two members I02 and I04, which are adjustable with respect to each other by means of a slot and screw connection I06. The rest bars I00 are connected with rods I08 and H0 at the ends thereof. The rod I08 is slidably and adjustably arranged in a bore of an arm I I2 mounted on the frame of the warper. A set screw II4 serves to holdthe rod I08 in the adjusted position. The rod H0 is slidably and adjustably arranged in a bore of an'extension I I6 of the adjustable supporting element 60 and is held in its position by a set screw II8. Thus, the rest bars I00 may be adjusted in a certain position with respect to a beam 44 by means of the rods I08, H0 and set screws H4, H8, while the length of the rest bars may be adapted to the width of the beam used by means of the slot and screw connection I06. Therefore, the warper may be used for beams of various sizes and shapes.

Fig. 4 indicates a beam 44 of usual form in dash and dot lines. The beam has flanges I20 and I22 at the ends of its hollow core I24, and the center hole I28 is provided with a longitudinal notch NOW, the insertion of an empty beam 44 into the warper shall be described. For this purpose the supporting elements 60 carrying the bracket 56 and the rods IIO of the rest bars I00 are brought into a predetermined position in accordance with the width of the beam to be inserted. Of course, if the supporting elements 60 are al. ready in the proper position, a'special adjustment thereof become superfluous. The bracket 58 is swung into the horizontal position shown in Fig. 5, whereupon the empty beam may be asily placed into the warper by sliding the flange I20 along the rest bars, until one end of the center hole I26 comes into engagement with the driving head 50. The conical shape of the driving head 50 facilitates the engagement and cause a, slight lifting of the flange I20 away from th rest bars I00. During the engagement of the driving head 50 with the center hole I28 of the beam, a key I30 arranged on the driving head is brought into engagement with the longitudinal notch I28 to establish a positive drive of the beam. Now, the

' bracket 56 is swung into its upright position shown in Fi 4, so that the idling head comes into engagement with the other end of th center hole I26. The idling head is also of conical shape, so that the flange I22 of the beam is slightly lifted away from the rest bar I00 to secure a free rotation of the beam. During the engagement of the idling head 80 with the center hole of the beam, the idling head may be shifted to a certain extent in the direction of the arrow A (Fig. 4) against the action of the spring 90, if the position of the supporting element 60 does not exactly correspond to the width of the beam inserted. In other words, the above described play of the idling head 80 and its shaft I8 allows for slight difference in the width of the beams of a certain standard size. After locking the bracket 56 in its upright position by means of the screw I0, the operation of the warper may be started.

In order to remove a full beam from the warper after the termination of the warping operation, the bracket 56 is swung into the horizontal position shown in Fig. 5, whereby the idling head 80 is disengaged from the center hole of the beam and the flange I22 of the beam drops onto the rest bar I00. Now, the operator has free access to the flange I22 and may easily remove the beam from the Warner by sliding its flange I20 along the rest bars I00.

According to Figs. 1, 2 and 8, a pressure roll I32 of a width somewhat smaller than the distance between the flanges I20 and I22 of the beam 44 rests against the windingv I34 on the beam. As best shown in Fig. 6, the pressure roll I32, which is selected in accordance with the standard size of the beam to be inserted into the warper, is exchangeably journalled in roller bearings I36 and I38 carried by arms I40 and I42 mounted on a rod I44 rotatably and shiftab ly arranged in bearings I46 and I48 of the frame of assess the warper, The longitudinal are 01 the rod 144' is substantially parallel to the longitudinal axis of thebeam 44. The arm I40 is fixed to the rod [44 in any suitable manner, while the'arm I42 is slidably and adjustably arranged on the rod I44, so that the distance between the arm I40 and the arm 142 may be adjusted in accordance with the width of the pressure roll I32 selected. The arm I42 is held in its position by means of a set screw I50. One end of the rod I44 projects fromthe frame of the warpeiand has a groove I52 for engagement with an adjusting plate I54 mounted' on the frame by means f'a cap screw :56 and a thumb screwfl'58. The adjusting plate I54 resting against springs I60 and I62 wound around the shafts of said screws serves] to hold the rod I 44 inc; predetermined position. The position of the adjusting plate and the shiftable rod I44 carrying the assembly of the arms I40, 142 and pressure roll I 32 may be varied to a certain ex tent by means of th thumb crew I 56, so that the pressure roll may be brought'into proper registering position with the beam. In other words, the described adjustment of the rod I44 carrying the pressure roll I32 by the adjusting means I54, I58 allows for slight diflerences in the Width of beams of a certain standard size.

The pressure roll I32 is pressed against the winding I34 on the beam by means of a weight I64 carried by an arm I66 secured to the rod I44.

A combined speedometer and odometer I68 (Figs. 1 and 6) mounted on the arm I42 serves to indicate the circumferential speed of the pressure roll I32 and the winding I34 and the length of the warp wound on the beam 44.

As best shown in Figs. 1, 2, 3, 6 and 7, a crank I keyed to the rod I 44 is pivotally connected with one end of an actuating member I12. The other end of the actuating member carries a roller I 14, which is in engagement with a cam I16 secured to a slidable carriage I18 by screws I80 (see also Figs. 8 and 12). A set screw I82 (Figs. 6 and '1) arranged on the actuating member I12 cooperates with an abutment I 84 on the crank I10 and determines the angle between the member I12 and the crank I10 as long as the pressure roll I32 contacts the winding I34 on the beam. A tension spring I86 stretched between hooks of the crank I10 and actuating member I12 tends to bring the set screw I 82 into engagement with the abutment I84 and to hold the roller I14 of the member I12 in cooperative engagement with the sliding cam surface I16.

As best shown in Figs. 3, 8 and 12, the carriage I18 has a groove I80 on each side thereof for engagement with four guide rollers I90 mounted on a member I 92 secured to the frame of the warper, so that the carriage may be moved through the distance c=a+b (see Fig. 3) by means of the controlling mechanism I10, I12, I14, I16, when the swingable support I40, I42, I44 carrying the pressure roll I32 is moved through the angle 'y=oz+fi during the building up of the winding I34 on the beam 44.

According to Figs. 8, 11 and 12, the carriage I18 has a channel I94 for receiving the main portion of a T-shaped holder I96 carrying the reed 42 of divergent shape in a manner to be described here inafter. The holder I96 is slidably arranged in the channel I94 for an adjustment of the reed 42 in vertical direction by means of an adjusting screw I98. Said adjusting screw passing through the hole of a lug 200 of the holder I96 and having a set collar 202, 204 on each side of the lug is screwed into the threaded hole of'a member 206 secured to'the carriage I18 -by screws 308. Aplate' 2'I0jmounted on the carriage by screws 2 I 2-serves to clamp the holder 196 against "the base of the channel I94.

' As best shown in Figs. 8 and 10, the frame of the divergent reed 42, the width of which increases from its lower portion'toward its upper portion, is inserted into a recess of a support 214' and is held in its position by screws H6; The

support .2I4 is connected with the head of the holder I96 by 'means of two slot and screw connections 2'I8, 220 for an adjustment of thereed 42 in horizontal direction by means of 'an adjusting screw 222. through the hole of a lug 224 of the support'2'I4 and having a set collar 226, 228 on each sideof the lug is screwed into the threaded hole of an extension 230 of'the head of the holder I96; Springs 232 wound around the shafts of the screws 220 and arranged between the holder I96 and the nut cause a certain friction to secure the position of the support 2I4 and the reed 42 with respect to the holder.

Furthermore, a bracket 234 is mounted on the slidable carriage I18 by means of screws 236 as best shown in Figs. 3, 8 and 11. Said bracket 234 has a recess 238 for receiving a holder 240 secured to the bracket by means of a screw 242. A membar 244 carrying a bar or table '246 is slidably arranged on the holder 240 and is held in its normal inactive position by means of a stop screw 248 which is screwed into the holder 240 and forms an abutment for an extension 250 of themember 244. Afterthe termination of the warping operation themember 244 and table 246 may be shifted into an upper active position 244', 246' as shown in dash and dotlines in Fig. 3 to bring the yarns of the warp 3'4 into a straight plane and facilitate the pasting of a striponto the warp before the. yarns are severed. A spring trigger 252 arranged on the member-"2 44 is automatically engaged with a'notch 254 on the holder 240 to hold themember 244 and the tab le246 inthe upper active position. A stop screw 256 arranged on the holder 240 limits the upward movement of the member 244 to prevent an undesired disengagement of the member 244 from the holder 240 I As best shown in Figs. 1, 3 and 8, two rods 235 and Y23'! of glass or any other suitable material for guiding the warp 34 are also mounted on the carriage I18. For this purpose two vertical supporting bars 239 carrying a member 24I having on each side thereof a horizontal supporting rod 243 secured thereto are secured to the bracket 234 mounted on the slidable carriage I18. Arms 245 carryingthe guiding rod 235 and arms 241 carrying the guiding rod 231 are rotatably and adjustably mounted on said supporting rods 243. The arms 245 and 241 are held in their positions by set screws or the like. 'Moreover, a rheostat 258 mounted on a stationarypart of the Warner and electrically connected with the field of the electromotor 46 by lines 260 is controlled by the slidable carriage 118 as best shown in Figs. 2, 3-, 7, 8 and 12. For this purpose, a rack 262 meshing with a pinion 264 keyed to the shaft 266' of the rheostat 258 is, secured to the carriag I18 by screws 268. Thus, an upward movement of the carriage I18 by the controlling mechanism I19, I12, I14, I16 owing to a movement of the swingable support I40, I 42 and the pressure roll I 32 through an angle 7 during the building, up of the winding onthe beam causes a rotation of the shaft of the rheostat 258, so that the operating speed of the Said adjusting screw passing shaft of the electromotor 46 and the beam 44 directly coupled therewith is automatically changed from a predetermined normal value to a lower value in order to obtain a substantially constant travelling speed of the warp yarns re--' sulting in a substantially constant tension in the warp yarns 'as the diameter of the winding I34 increases.

Assume, at the start of a warping operation the adjustable divergent reed 42 is set'in such a way, that the warp 34 (indicated by dash and dot lines in Fig. 8) passes between the points (1 and e of the reed. During the buildingup of the winding I34 on the beam the diameter of the winding is increased, so that the warp is lifted from a lower level into a higher level, for example, from the position 34 into the position .34 asshown in Fig. 7. At the same time, the swingable support I40,'I42 carrying the pressure roll I32 is moved through the angle 7, so that the carriage I18 supporting the reed 42 is lifted by means of the controlling mechanism I18, I12, I14, I18 through the distance (see Fig. 3). Preferably, the members of the controlling mechanism are arranged and shaped in sucha way, that the lifting of the reed corresponds to the lifting of the warp and the latter always passes between the two points d and e of the reed.

Obviously, the guiding rods 235, 231 and the table 246 connected with. the carriage I18 are liftedsimultaneously with the reed '42. Such a lifting of the guiding rods 235, 231 in dependence on the building up of the windin On the beam 44 eliminates a change in the angle between the warp yarns 34 and said guiding rods, so that the tension in thewarp yarns remains substantially constant during the operation of the warper, with the result of a uniform winding on the beam.

If, after the start of the warping operation, the operator should find out, that the yarns of the warp are not uniformly distributed over the width of the beam inserted into the warper, the desired uniform distribution of the yarns may easilybe obtained by a-slight re-adjustment of the reed 42 in vertical and/or horizontal directionby the adjusting means I98, 202 and/or 222, 228.

When the warping operation is terminatedand the warper is arrested, the pressure roll is in the position I32" indicated by dash and dot lines in Figs. 1 and 7. According to Fig. '1, the pressure roll then is still between the flanges of the beam 44. In order to render possible the removal of the full beam in the direction of its longitudinal axis as described above, the pressure roll should be further swung by hand into the position shown in full lines in Fig. '1. For this purpose, a handle 210 is arranged on the arm I42 (see Figs. 1 and 6). During this manual swinging of the pressure roll from the position I32 (Fig. '7) in clockwise direction, a further lifting of the reed 42 and the table 246 is undesired, as the warp remains in the same level. Therefore, adjustable means are provided for rendering inoperative the controlling mechanism I10, I12, I14, I16when, after the termination of the warping operation, the pressure r011 I32 is moved away from the winding on the beam. As best shown in Figs. 2, 3, and 8, an adjustable set screw 212 is arranged on the member I92 for cooperation with an abutment 214 secured to the slidable carriage I18. The adjustable set screw 212 may be set in such a way, that the abutment 214'. contacts the set screw substantially simultaneously with the stoppage. of the warper, when, for example, the pressure roll and the members of the controlling mechanism are in the position shown in dash and dot lines in Fig. '7, i. e. the pressure roll is in the position I32". Now, when the pressure roll is moved away from the winding on the beam and the pressure roll and the crank I10 are swung into the position shown in full lines in Fig.1, the carriag I18 and the cam I18 mounted thereon are arrested by the set screw 212, so that the actuating member I12 is swung about the pivot between said member and the crank I10 against the action of the spring I86, while the roller I14 of the member I12 slides along thesurface of the cam I16. Thus, the controllingmechanism I10, I12, I14, I16 is rendered inactive, and the swinging of the pressure ,roll away from the winding on the beam does not cause a further lifting of the reed and the table. If it is desired to produce a winding of a diameter smaller than that shown in Fig. 7, the position of the set screw 212 is changed in such a way, that the abutment 214 contacts the screw 212 after a short stroke. Thus, the stopping means 212, 214 may be adjusted for windings of various diameters.

In order to hold the pressure roll I32 in the extreme position shown in Fig. '1 against theaction of the weight I64 and the spring I86 .during the exchange of a beam, the following automatic locking mechanism is arranged. According to Figs. 3 and 6, alocking rod 216 carrying two set collars 218 and 280 is shiftably arranged in stationary bearings 28 2 and 234. A spring 288 arranged between the bearing 284 and the set collar 280 tends to urge the set collar 218 against theb'earing 222,50 that the end 288 of the rod 216 extends into the path of a cam 290 arranged on the crank I 10 keyed to the shaft I44. The other end of the spring loaded locking rod 215 projecting from the frame of the warper carries a knob 292 secured thereto. During the warping operation of the device, the locking rod 216 mm a level above the cam 290. When, at the end of the warping operation, the crank I10 and cam 290 reach the position shown in dash and dot lines in Fig. '7 the locking rod 216 is still above the. earn 290'. Now, when the pressure roll I32 is moved away from the beam and the crank is swung into the position shown in full lines in Fig. '1, the inclinedsurface of the cam 290 contacts the locking rod 210 and displaces same against the action of the spring 286, whereupon, after disengagement of the inclined surface of the cam from the locking rod, the spring 286 returns the locking rod into its normal position now below the cam 290, so that the locking rod 216 comes into engagement with the straight locking surface 294 of the cam 29;; and holds the pressure roll I32 in its extreme position. In order to release the pressure roll after the exchange of a beam,- the locking rod 210 is pulled out against the action of the spring 280 by gripping the knob 292. Then, the pressure roll may be returned into its starting position, whereupon the locking rod 216 may be released, so that the latter is automatically returned by the spring 286 into the position'above the cam 290 as shown in Fig. 6. I 4

The warper shown in the drawings has a first brake associated with the drive and a second brake associated with the pressure roll, and means are providedfor causing'a substantially simultaneous application of said two brakes when the warper isarrested.

According to Figs. 2, 3 and 4 a portion of the drive head 53 keyed to the shaft 520i the electromotor 43 is in the form of a brake drum 294. One end of abrake band 296 embracing said drum is secured to a stationary element 298, the other end of said brake band secured to an arm 330 of a double armed lever 302 pivoted to the element 333 at 334. A tension spring 383 stretched between the other arm 338 or the double armed lever 332 and an extension 323 oi the stationary element 298 tends to turn the double armed lever 392 in counter-clockwise direction as viewed in Fig. 3 to hold the brake in released condition. The rotation of the lever 3&2 in counterclockwise direction is limited lug 382 of the lever 392 adapted to abut against a projecting portion of the stationary element 298. The arm 3% of the lever is hinged. to one end of a link 354, the other end of which is pivoted to the core3i of a solenoid 353 electrically connected with the electrical braking control means as fully clescribed in my Patent $2,324,612 relating to a "Warping or beaming machine An energizzn tion of the solenoid 318 causes a movement of the lever 302 in clockwise direction for an application of the brake 294. 296.

According to Figs. 3 and 4, a ring 329 of leather or any other suitable material is mounted on the surface of the brake'drum 234 facing the flange I20 of the beam. When a beam is inserted into a warper, the flange I29 is pressed against said ring 320, so that the ring assists in the driving of the beam by friction.

As best shown in Figs. 3 and 6, brake drum 322 is secured to ahub 324 of the exchangeable pressure roll I32. When the pressure roll is" inserted into the bearings on the supporting arms I40, I42, a brake band 326 may be placed around the drum 322. One end of said brake band 326 is connected with a lug 328 on the arm I49, the other end of said brake band is connected with one end of a'compensating means or tension spring 330 having its other end connected with a crank 322 keyed to a shaft 334 journalled in a bearing 336 of the arm I46. A tension spring 338 stretched between a pin 340 arranged on the arm I 40 and an arm 342 keyed to the shaft 334 tends to move the crank 332 in clockwise direction as viewed in Fig. 3 to hold the brake in released condition.

The first brake 294, 296 associated with the drive of the warper and the second brake 322, 326 associated with the pressure roll are coupled with each other by means of a Bowden wire 344. One end 346 of said Bowden wire is secured to the arm 308 of the double armed lever 362, while the other end 343' of the Bowden Wire is connected with the arm 342. Thus, an energization of the solenoid 3! causes an application of the first brake 294, 296 and, substantially at the same time, an application of the second brake 322, 326 through the medium of the Bowden wire and the tension spring 336 compensating for differences in the brakes. On the other hand, a deenergization of the solenoid 318 permits a movement of the lever 332 in countenclockwise direction by the spring 306 for an automaticrelease of the two brakes. Of course, any other coupling between the two brakes and any other compensating means arranged between the two brakes could be used, if desired.

As pointed out above, the rheostat 258 serves to cause an automatic reduction of the operating speed of the driving. electromotor 46 from a predetermined normal degree to a lower degree, so that a substantially constant travelling speed of the warp yarns resulting in a substantially. constant tension in the yarns is obtained during. the operation of the warper. The normal travelling speed of the warp yarn is determined by said predetermined normal operating speed of the electromotor at the start of the warping operation. Different yarns of difierent size and/or material require different travelling speeds to obtain the proper tension in the yarns. Therefore, an additional electrical adjusting means or a hand rheostat 3513 (see Figs. 1 and 2) is arranged on the warper for the adjustment of said predetermined normal operating speed of the driving electromotor 46.

It has been found that a wide speed range of the electromotor 46 directly coupled with the drive 53 of the beam may be obtained by using a D. C. electromotor and connecting the hand rheostat 350 with the source of direct current in such a way, that the rheostat 353 controls the voltage of the direct current supplied to the electromotor of the warper. I

As willbe apparent from the description of the warper, the warper has the following features: The bracket 56 carrying theidling head is adjustably mounted on the rods 64 so as to permit the insertion of beams of various widths,

the pressure roll I32 is exchangeable so as to permit theselection of a pressure roll capable of cooperation with a beam of predeterminedwidth, and the divergent reed 42 is adjustable in horizontal and vertical direction. Therefore, the warper may be used for winding yarn in various gauges, i. e. number of yarns per inch,.on beams of various widths as will be explained hereinafter in connection with Figs. 13-15.

If, for example, the warper has been used previously for warping yarn, in a gauge of 30 yarns per inch on a beam of a width of 10", and if, during the next warping operation, the warper shall be used for warping yarn in the same gauge of 30 yarns per inch on a smaller beam of a width of 8", the following steps are carried out: As sume, during the previous warping of the yarn on the IO'f-beam, the beam 44, the bracket 56 with the idling head 80, and the reed 42 are. in the position shown in full lines in Fig. 13, and a warp of 300 yarns passes between the points i and y of the reed. Now, the bracket with the idling head is brought into the dash and dot line position 56', 80', so as to permit the insertion of an 8-beam 44; the motor 46 and the driving head 50 coupled therewith remain in their position' A pressure roll capable of cooperation with an 8".- beam is substituted for the pressure roll used previously. The reed 42 remains in its position. 60 yarns are taken away from the warp, so that a warp of 240 yarns only passes between the points 1 and m of the reed 42, said points being spaced from each other at a distance of 8". Therefore, the beam of a width of 8" receives 240 yarns per 8", or, in other words,v the yarns are wound on the 8"-beam in the same gauge of 30 yarns per inch, as they have been wound previously on the l0"-beam.

If, for example, the warper has been used previously for warping yarn in a gauge of 30 yarns per inch on a beam of a width of 10", and if, during the next warping operation, the warper shall be used for warping yarn in a difierent gauge of 25 yams per inch on a beam of the same width of 10'', the following steps are carried out: As-

sume, during the previous warping of the yarn on the 10"-beam, the beam 44, the bracket 56 with the idling head 80, and the reed 42 are in the position shown in full lines in Fig. 14, and a warp of 300 yarns passes between the points I and g of the reed. Now, the bracket with the idling head remains in its position relative to the rod 64 so as to permit the insertion of another 10"- beam. The pressure roll is not exchanged. The reed 42, however, is brought'into the position 42' as shown in dash and dot lines in Fig. 14, so that the point It takes the place of the point I and the point 1 takes the place of the point g. Furthermore, 50 yarns are taken away from the warp in the space between the points i and k, so that a warp of 250 yarns passes between the points 71- and i of the reed in the position 42', said points being spaced from each other at a distance of 10". Therefore, the beam of a width of 10 receives 250 yarns per 10", or, in other words, now the yarns are wound on the 10" beam in a gauge of 25 yarns per inch. In order to move the reed from the full-line position 42 into the dash and dot line position 42', preferably at first the reed is shifted in a vertical direction Y (see Fig. so that it comes into the intermediate position 42" as shown in dash lines, whereupon the reed is moved from said intermediate position 42" into the new position 42', in a horizontal direction Z. Of course, the horizontal and vertical adjustment of the reed could be reversed or carried out simultaneously, if desired. j

Although preferably the individual objects of the invention are applied to a warping plant in the combination described, the individual objects of the invention may be applied individually or in partial combination to warping or beaming machines. It is emphasized that the merits of the invention are not limited to the described and illustrated combination, but the individual objects of the invention per so also have inventive merits. Without stating that all the individual objects of the invention are enumerated, it may be mentioned that, for example, the direct coupling between the driving electromotor and the driving means of the beam could be arranged in a warper, which is not equipped with means permitting the insertion of the beam in the direction of its longitudinal axis, or that themeans for adjusting the warper to the size of the beam to be inserted could be arranged in a warper which has no direct coupling between its drive and the driving means of the beam, or that the controlling means for lifting the reed in accordance with the increase of the diameter of the winding on the beam could be arranged in a warper wherein the automatic controlling means for reducing the speed of the drive are separated fitom said controlling means for lifting the reed, e c.
